class XOR_operator {
public static void main(String[] args) {
System.out.println("xor " + ((true) ^ (true)));

Result = False ??? WTF .. how this operator works ?

The "x" in "xor" means "exclusive."

So a^b is true if a is true or b is true, but not if both are true (because then it wouldn't be exclusive).

Or as JLS - 15.22.2 puts it, "the result value is true if the operand values are different; otherwise, the result is false."
